项目摘要

The defective inter-domain interaction between N-terminal and central domains within RyR2 reduces the binding affinity of CaM to RyR2, thereby causing the spontaneous Ca^<2+> release events in diseased hearts. Correction of the defective CaM binding may be a new strategy to protect against the aberrant Ca^<2+> release in heart failure and lethal arrhythmia.
RyR2内的N端和中心结构域之间有缺陷的结构域间相互作用降低了CaM与RyR2的结合亲和力,从而导致患病心脏中自发的Ca 2+ 释放事件。纠正有缺陷的CaM结合可能是防止心力衰竭和致死性心律失常中异常Ca 2+ 释放的新策略。
